Milk is often measured by cups in recipes, but grams are useful when you are baking by weight or scaling a formula. One US cup of milk is commonly estimated at about 245 grams.
This page is designed for dairy milk such as whole milk, 2 percent milk, 1 percent milk, or skim milk. Plant-based milks can be close, but exact weights may vary by brand and ingredients.

How to Convert Milk Cups to Grams
To convert milk from cups to grams, multiply the number of cups by 245. This page uses 1 cup of milk = 245 grams, which is a practical average for everyday baking.
grams = cups x 245 For example, if a recipe calls for 2 cups of milk, the calculation is 2 x 245 = 490 grams. If it calls for 1/2 cup, the calculation is 0.5 x 245 = 123 grams.
How to Convert Milk Grams to Cups
To convert milk from grams to cups, divide the gram amount by 245. This is useful when a recipe gives metric measurements but you want an approximate cup measurement.
cups = grams / 245 For example, 100g of milk is 100 / 245 = 0.41 cups. This is close to 6.5 tablespoons. Grams are still more reliable than cups because small measuring differences can change the texture of the final recipe.
Why Milk Cup Weight Can Vary Slightly
Milk is mostly water, so its cup weight is fairly consistent. Fat level, added solids, foam, and temperature can create small differences.
Whole milk, reduced-fat milk, and skim milk are close enough for everyday recipe conversions. This calculator uses 245g per US cup as a practical average.
How to Measure Milk Accurately
For the most accurate measurement, place your mixing bowl on a digital scale, tare it to zero, and pour milk directly into the bowl until you reach the gram amount.
If you use a liquid measuring cup, set it on a flat surface and read the line at eye level. Avoid measuring foamy milk because bubbles can make the volume look higher.
When a recipe uses both milk and flour, weighing both ingredients helps keep the batter texture more predictable.
Milk Cooking and Baking Notes
Milk adds liquid, protein, lactose, and richness. It helps pancakes, cakes, muffins, sauces, custards, and breads develop flavor and texture.
The fat level can affect richness, but the gram conversion is close for most dairy milks. If a recipe specifically calls for evaporated milk, condensed milk, or cream, use a separate conversion.
For yeast doughs and custards, milk temperature can matter. Follow the recipe instructions for warm, room-temperature, or cold milk.
Milk vs Water and Cream by Weight
Milk is slightly heavier than water by cup. This calculator uses 245g per cup for milk, while water is commonly treated as about 237g per US cup.
Cream, evaporated milk, condensed milk, and yogurt are not the same as milk because they contain different amounts of fat, solids, and sugar.
If a recipe calls for yogurt, honey, or peanut butter, use the matching converter because those ingredients have very different cup weights.
